Abstract

Valve arrangement in a pressure medium line, which can be used as feed line and return line, the said valve arrangement being intended to control the flow in the said line and comprising a valve body, which has a first and second valve opening, which alternatively function as inlet opening and outlet opening, and a valve spindle arranged on the valve body, which spindle in its open position connects the valve openings to one another and in its closed position closes them, and which is acted upon by a holding force that is greater than the force acting on the side of the valve spindle that is on the pressure medium side and is dependant upon the pressure medium prevailing in the feed opening. In order to allow a flow in both directions, the valve openings 2, 3 are connected to a chamber 17 by way of a duct 19, 20 for each of them and by way of a groove 18, which functions as an adjustable limiting element in the valve spindle, each of the ducts 19, 20 containing a valve 21, 22, which allows a flow from the valve openings 2, 3 to the chamber 17, which is in turn connected to the valve openings by way of the ducts 23, 24: 23, 25, which both have a valve 27, 28, which allows a flow from the said chamber and contains a regulating valve 26 upstream of the latter valves in the direction of flow, for closing and opening the flow from the said chamber 17. <IMAGE>
